Perfectly understandable to me. I don't have much money either. I'll likely only contribute again if its some reward I like that I can afford.

Paypal is mostly important, I think, so that people who completely missed the Kickstarter can slowly trickle in. (I know this since I totally missed the Dreamfall Chapters Kickstarter but was still able to pledge on their site!)

I'm more pointing this out because you have to pay to join Something Awful (or even to read the forums, if the paywall is up), I'm hoping it may get some people to donate via Paypal, if they didn't have a chance to donate to the Kickstarter.
